Foreword

ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.

The procedures used to develop this document and those intended for its further maintenance are described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the different types of ISO documents should be noted. This document was drafted in accordance with the editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).

Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of any patent rights identified during the development of the document will be in the Introduction and/or on the ISO list of patent declarations received (see www.iso.org/patents).

ISO 15746-1:2015(E)

Introduction

As a crucial part of manufacturing systems with increased complexity, the automation and control applications enabled by advanced process control and optimization (APC-O) methodology and solutions perform the operations directed by production planning and scheduling. ISO 15746 deals with the integration of APC-O with manufacturing operations management (MOM) and with automation and control of manufacturing process and equipment.

The following IEC 62264 functionalities related to manufacturing are hierarchically structured in a functional model, as shown in Figure 1.

a) Level 0 defines the actual physical processes.

b) Level 1 defines the activities involved in sensing and manipulating the physical processes. Level 1 typically operates on time frames of seconds and faster.

c) Level 2 defines the activities of monitoring and controlling the physical processes. Level 2 typically operates on time frames of hours, minutes, seconds and sub-seconds.

d) Level 3 defines the activities of the work flow to produce the desired end products. It includes the activities of maintaining records and coordinating the processes. Level 3 typically operates on time frames of days, shifts, hours, minutes and seconds.

e) Level 4 defines the business-related activities needed to manage a manufacturing organization. Manufacturing-related activities include establishing the basic plant schedule (such as material use, delivery and shipping), determining inventory levels and making sure that materials are delivered on time to the right place for production. Level 3 information is critical to Level 4 activities. Level 4 typically operates on time frames of months, weeks and days.

Figure 1 — Functional hierarchy

ISO 15746 mainly focuses on the integration of APC-O capabilities into control activities (Level 2) and MOM (Level 3), in Figure 1.

BS ISO 15746-1:2015

ISO 15746-1:2015(E)

The APC-O system within Level 2 interacts with the MOM system of Level 3. It shall provide the information of the production processes to the MOM system, and in return accepts and executes the corresponding operational commands from the MOM system. The APC-O system within Level 3 samples measurement signals and monitors behaviour, and in return controls the operational systems within Level 2.

Automation solutions composed of software and hardware are provided by different suppliers to accomplish APC-O capabilities. Due to the diversity of development environments and the variety of demand focus, the automation solutions from various suppliers are isolated and relatively independent. These differences make the integration of automation solutions difficult. Consequently, the customers may purchase different automation solution components with redundant and duplicated functions, resulting in a waste of resources and limited interoperability. This part of ISO 15746 offers a reference interoperability framework for APC-O. It is intended to maximize the integration and interoperability of automation solutions.

This part of ISO 15746 is intended to help:

— identify an approach to assist the providers and system integrators of APC-O systems and related automation solutions components in verifying the interoperability of the components used to construct the automation solutions to meet application lifecycle requirements during designing, developing, implementing, testing, validating, installing and maintaining the automation solutions;

— identify the criteria to help users in choosing the appropriate automation solutions, such as APC-O modules, to meet their requirements;

— outline the concepts and conceptual framework elements that will be sufficient to address the identified problems and opportunities;

— reduce the time and cost in defining and describing the application requirements, as well as, in developing and implementing automation solutions based on APC-O systems.

The target users of this part of ISO 15746 include users and providers of the APC-O solutions, such as project solution suppliers, automation systems integrators, production departments of companies, process engineers, independent software testing organizations, implementation and consulting service organizations of APC-O software, and relevant governments and academic organizations.

Automation systems and integration — Integration of advanced process control and optimization capabilities for manufacturing systems —

Part 1: Framework and functional model

1 Scope

This part of ISO 15746 establishes a framework and general functionality of a method for integration of advanced process control and optimization (APC-O) capabilities for manufacturing systems. The goal is to reduce the cost and risk associated with developing and implementing integrated APC-O capabilities.

The scope of this part of ISO 15746 is limited to specifying the set of concepts, terms, definitions and the associated rules for describing the required functional capabilities of APC-O units.

The following are outside the scope of this part of ISO 15746:

— definition and specification of an interface or communication protocol between APC-O capabilities;

— requirement and restriction of a specific technical specification when developing and implementing APC-O systems;

— strategy and method of a certain APC-O system.

2 Termsanddefinitions
